fix(ui2): cursor flicker in cmdline with matchit #41245

Browse Source 
Problem:
The cmdline_hide callback causes an unnecessary cursor move to the cmdline,
before the normal redraw updates the cursor back to the current window. This
appears as "flicker" when using plugins such as matchit (legacy ":" mappings
instead of "<cmd>" mappings).

Solution:
Skip the immediate redraw for cmdline_hide events. The normal redraw
still updates the cursor after the cmdline window is hidden.
